` This invention relates to grease dispensing containers and has for its object the provision of a container which may ,be used for shippin grease or similar material and which can rea 'ly be changed into a self-dispensing container by the retail user.f In so far as I am aware, in spite of the demand for a device of this character the present means of marketing grease'such as the hardoil used for automobile and other bearings is to ship the same in an ordinary container and then in utilizing it to remove the head ofthe container and scoop the lubricant out from time to time as it is required. This has the difficulty 15 of leaving the barrel or container openl to the dust and other impurities and occasions considerable loss of time and a waste of the lubricant.

It is the purpose of this invention ,to pro- '2e A more specific'purpose ofthis invention is to provide in connection with the shipping container a dispensing head which carries means for readily attaching itto the shipping container upon removal of the l'shipping head and a plunger for forcing the contents ofthe container outwardly at the bottom thereof when air pressure is applied above the plunger through the dispensing head.

Other and more specific objects and advantages of the invention will appear as the' description proceeds when takenin connection with the accompanying drawings; however, I wish it to be distinctly understood that I ldo not intend' to limit myself to the exact details shown and described, but that I am to avail myself of all such modifications as would occur toone skilled in this art and as fall within the scope of the claims.

In the drawings: s Fig. 1 is a sectional v iew taken through the shipping container; s

Fig. 2 is a similar sectional view with the shipping head removed and the dispensing 50 head in place thereon and furthershowing and which carries in addition a guide member s ing or denting the body thereof.

to` lit in the recess 9 at its lower .end so as to.

tion 6 and the inset bottom portion 7. The

bottom forms with the portion 6 a pocket 8 for a purpose which will presently appear.

Centrally disposed in the bottom 7 is the recess 9 andat one side of the recess 9 is provided an outlet opening'lO normally closed by a plug 11. The top of the container 5 as 9 shown in Fig.'1 has an outwardly extending flange 12 upon which the outwardly extending flange 13 of the shipping head or cover 14 is adapted to rest. This cover 14 as shown is depressed inwardly ofthe flange 13 so as to 7" t, snugly within the top of thecoptainer. The two ilanges 12 and 13 are held rigidly in engagement by means of a solid ring 15 andk the split ring 16 consisting of the vhalves 17 and 18 as shown clearly in Fig. 4. These flanges and rings are provided with closely spaced bolt holes adapted to freceive the clamping bolts 19. Thus, when^the head 14 is applied as shown in Fig. land the plug 11 is in place, the container 5 forms a tight ships .ping container' in which' lubricant may be transportedw from place to, place. The out,-

wardly eztending flanges 6 and 12 form rolling edges on which the containermay be run in loading or unloading it so as to'avoid bend- Now, when the container is received by lthe retailersof 'the lubricant, the shipping head/or closure 14 is removed and a dispensing head 20' is substituted lfor it. This dis- 9 pensing head is secured in substantially the same manner as the head 14 and carries a guide rod-21-extending centrally therefrom downwardly into the container and adapted 4be held against lateral movement.. This i guide rod 21 in turn has slidably mounted thereon thepiston or plunger 22 which has an elongated hub or bearing 23 engagin the rod 21 to prevent wabblingor tip in o plunger within the container. A exi le cup leather 24 is mounted in the rim' of the plunger and projects downwardlytherefrom toward the bottom oit' the container. 'llie plug ll is removed and replaced by the pipe section 25 communicating with the strainer casing 26, an outlet controlled valve 27', through a metering device 28 to the discharge pipe 29. This may lead to any place Where itis desired to use the lubricant.

it will be noted that the dispensing head 2O is concave on its lower` surface so as-to bent out otn proper shape.

permit the plunger 22 and its elongated hub -23 to move up closely against the head 20 in slitting the dispensing head to a full container. lhe dispensing head is also provided with an inlet 3G to which an air hose 3l may be connected so as to supply air pressure Within the container to force the plunger down- Wardly and torce the lubricant in the container out through the discharge opening..

is the plunger approaches the bottom ofthe container, the@ cup leather 24 as it extends doi/vn below the lower face of the plunger would, unless some provision were made for it, be doubledup beneath the plunger and ln order to avoid this, the recess 8 is provided which permitsl the cup leather to expand outwardly as the yplunger approaches the bottom of the coiitainer as 'shown in Fig. 3 and this avoids any doubling or breaking ofthe cup leather.

Fromthe above description, it is thought that the construction and the 'use of my imu proved dispensing container Will. be clear to those skilled in this art. However, a few of the uses to which this device may be put is in the lubrication of machinery such as mine car Wheels Whichurequire only a low press-ure somewhat less than 200` pounds per square 'inch to force the lubricant in the bearing to be lubricated, also lubricating automobiles and similar machinery by using a iiexible hose on the end of the discharge pipe with the lever type booster pump and the coupling on the end of the flexible hose similar to the Well known alemite type;l alsoy in lubricating` container. i u o Having thus described my invention,-

Awhat I claim and desire to secure by a piston guide rod rigidly securedthereto vvand extending to .the bottom of said container, receiving means in'thebottom of said container into engagement with which the lower end of said guide rod is slidable to hold the same against lateral movement, ailunger. freely slidable on said guide rod an means von said head for admitting air under presysure into said container above said plunger, said plunger having a Hexible sleeve secured to the rim thereof and said container having an annular recess at the lower' end thereof to receive said sleeve.

2. A grease storing and dispensing conso I tainer comprising a substantially cylindrical l shell, a closure permanently closing one end of said shell and forming With the end or said shell an outwardly extending rim adapted to serve as a rolling edge Jlor said shell and forming within said rim an annular recess ci greater diameter than said shell, said closure having an outlet aperture therein, a removable head ior the other end of said con-' tainer having a guide rod secured thereto and extending to said closure, a plunger freely slidable on said rod, and. an annular flexible member on said plunger adapted to entend into said recess when said plunger is inits lowermost position.

3. A combined shipping container and grease dispensing head comprising a substantially cylindrical shell having a permanent closure at one end foiniedl with .an outlet aperture and having seating means thereinl of said container readily attachablethereto, v

said closure having rigidly mounted thereon a guide rod which extends the length of said;

container and engages said seating means, a piston sli'dable on said rod, and means On said second named closure to admit air'above 'said piston, said permanent closure and seating means permitting said piston to move substantially'into engagement with the inner surface of said permanent closure whereby to expel practically all .of the contents of said container.V i

In Witness whereof l hereunto' subscribe my ianie this fourth day of November A. D. 192 i' Y BAYARD W. MENDENHALL.
